Answer:
Impact of gesture learning on students performance (correct answers) can be done through Hypothesis Testing
Explanation:
The hypothesis test is to check that impact of learning with gesture, increases or not the average number of correct answers by students.
Let : Group 1 = No gesture ; Group 2 = Gesture
Group 1 : no. = n1 , mean = u1 , standard deviation = σ1
Group 2 : no. = n2 , mean = u2 , standard deviation = σ2
Null Hypothesis [H0] : Mean (Group1) = Mean (Group2)
Alternate Hypothesis [H2] : Mean (Group 1) < Mean (Group 2)
Let level of significance α = 5% = 0.05
Test t statistic = ( <u>u1 - u2</u> )
√ [ σ / n1 + σ
/ n2 ]
If calculated value of this 't' > tabulated 't' i.e usually 1.96 at α = 0.05 or if p value < 0.05 : We reject the null hypothesis & conclude that Mean (Group 1) < Mean (Group 2). This implies that theory learning with gesture implies higher average correct responses
If calculated value of this 't' < tabulated 't' i.e usually 1.96 at α = 0.05 or if p value > 0.05 : We don't reject the null hypothesis & conclude that Mean (Group 1) = Mean (Group 2). This implies that theory learning with gesture doesn't imply higher average correct answers
